Kudzu Bug Thresholds

Soybeans 002

Soybeans are in the county are flowering now moving into the reproductive (R6) growth stage. I got reports last week of kudzu bugs and found some Monday. According to UGA Extension Entomologist, Dr. Phillip Roberts, kudzu bugs populations have been lower in the state overall this year.

We still want to watch for nymphs but try not to spray tooearly. At least two generations occur each year; it takes 6 – 8 weeks for a kudzu bug to complete its lifecycle. Because of this, spray timing should interrupt the development of lifecycle by targeting immatures. The threshold is one nymph per sweep or many nymphs present visually.
